“…The concentration of Ca in tested nuts, except almonds, was lower than in nut samples from various countries, including Serbia, RPA, Chile, USA or Brazil [ 1 , 18 , 21 , 67 , 68 , 69 ]. The calcium content in tested almonds was higher in nuts from Serbian market (1491–1506 µg/g) and lower than in samples from RPA (5392.4 µg/g) and USA (3550 µg/g) [ 1 , 18 , 67 ].…”

“…The calcium content in tested almonds was higher in nuts from Serbian market (1491–1506 µg/g) and lower than in samples from RPA (5392.4 µg/g) and USA (3550 µg/g) [ 1 , 18 , 67 ]. The magnesium content in examined cashews (3449.93 µg/g), peanuts (2307.71 µg/g), hazelnuts (3168.56 µg/g) and pine nuts (4372.49 µg/g) was higher than in nuts from Serbian market (cashews, 2297–2444 µg/g; hazelnuts, 1497–1524 µg/g; peanuts, 2036–2079 µg/g) and from Brazilian pine nuts with Mg content equal 513 µg/g [ 18 , 68 ]. In contrast, the Mg content in macadamia nuts, pecans and pistachios from Polish market was lower than it concentration in nuts described in literature data [ 1 , 18 ].…”

“…Literature data also confirms the large variation in the content of these macronutrients in the samples of nuts from different region of the world. The Na content was in a range from 50.8 µg/g for Brazilian pine nuts to 6848 µg/g for Serbian peanuts, while K concentration was determined in a range from 37.52 µg/g (peanuts from Serbia) to 8704.6 µg/g (Brazilian pine nuts) [ 18 , 68 , 70 ].…”

“…According to literature reports, the Fe content in edible nuts was in a range from 19.60 µg/g (pine nuts) to 105.86 µg/g (pecans) [ 1 , 74 ]. However, the most frequently the Fe concentration in various nut samples was in the range 40–80 µg/g, and at this content level was determined in almonds, Brazil nuts, cashews, pistachios, walnuts and macadamia nuts [ 1 , 12 , 18 , 68 ]. In tested nuts, selenium was determined in all samples in trace amounts (0.88–1.14 µg/g), except for Brazil nuts, which had a higher Se content (11.27 µg/g).…”

Edible nuts are an important component of a healthy diet, and their frequent consumption has beneficial impact on human health, including reducing the risk of cardiovascular and neurodegenerative diseases. Moreover, various factors, including cultivar, climate, soil characteristic, storage and treatment have influence on the chemical composition of nuts. Therefore, nine tree nut types and peanuts commonly available on Polish market were evaluated for phenolic profile and mineral elements content. The concentration of individual phenolic compounds, including flavonoids, aromatic acids and caffeic acid phenethyl ester (CAPE) was determined by ultra-high pressure liquid chromatography, while the content of macro-elements and trace minerals was analyzed by atomic absorption spectrometry. The phenolic profile of analyzed nuts substantially varied depending on the type of nut. The highest total content of all analyzed flavonoids was determined in walnuts (114.861 µg/g), while the lowest in almonds (1.717 µg/g). In turn, the highest total content of all tested aromatic acid was determined in pecans (33.743 µg/g), and the lowest in almonds (0.096 µg/g). Epicatechin and cinnamic acid were detected in the highest concentration in tested nuts. Moreover, in examined nuts (except walnuts and Brazil nuts), the presence of CAPE was confirmed. The tested nuts were also characterized by wide variation in element concentrations. Almonds contained high concentration of macro-elements (13,111.60 µg/g), while high content of trace elements was determined in pine nuts (192.79 µg/g). The obtained results indicate that the tested nuts are characterized by a significant diversity in the content of both phenolic compounds and minerals. However, all types of nuts, apart from the well-known source of fatty acids, are a rich source of various components with beneficial effect on human health.

“…The other municipalities ranged between these two localities and were not statistically significant. On the other hand, the resistant starch contained within the total starch did not vary statistically (p < 0.05), and the values obtained were on average 4.3 ± 0.5 g/100 g. The differences in total starch values can be attributed to the higher protein content present in the LAP sample (8.00 g/100 g), as can be seen by (Silva et al, 2022) whose data corroborate that the pinhão almonds present higher carbohydrate content, but a significant protein content. Foods containing resistant starch are of importance for human consumption, as this nutrient is a kind of soluble dietary fiber and is resistant to digestive enzymes of the upper digestive tract, bringing health benefits such as preventing disease processes, including cancer of the colon diabetes and obesity (Bai et al, 2021).…”

The effect of harvest location on cooked pinhão seeds (Araucaria angustifolia) was investigated with regard to its centesimal composition, minerals, and color, and later correlated with environmental and soil variables.Significant differences between cooked pinhão from various harvesting locations were seen; also, principal component analysis was performed for the minerals, protein, moisture, total starch, and color parameters. The geographic location was one of the most important factors. Caçador presented greater differences: lower values for moisture, minerals, geographic parameter, and color characteristics. However, nearby localities, such as Cruz Machado with Bituruna and Lapa with São João do Triunfo, presented similar overall values for minerals and geographic parameters. Each regional geographic location was able to present unique characteristics so that the principal component analysis categorized it in specific quadrants, which is also in agreement with the CIELAB color space. However, hierarchical tree exhibited that CAÇ was the most distinct, due to the most distant municipality, presenting a unique microbiome. The pinhão is a source of various nutrients, which contributes to healthy dietetic daily values.It provides from 20% to 30% of dietary fiber, Cu (42.2%), P (31.1%), K (23.5%), and Zn (22.1%), while also providing quantities of Mg (12.9%), Mn (12.4%), Fe (11.5%), and Ca (6.4%). Therefore, it is possible to obtain food products based on cooked pinhão that contain many nutritional components associated with human health benefits.

SummaryLarge low Earth orbit satellite constellations require machine learning methods for enabling autonomy in health keeping of the satellites. Autonomy in health keeping entail's fault detection, isolation and reconfiguration. However, prior to model building, it becomes imperative to conduct exploratory data analysis of the data to gain an intuition of data and to decide the best model. Univariate exploratory data analysis has been carried out on a BUS CURRENT sensor of electrical power system of a low Earth orbit satellite to gain an understanding of data. Various aspects of data like presence of outliers, sampling frequency, missing values, comparison of imputation methods to fill missing values seasonality and trend analysis, stationarity test on data, rolling mean and autocorrelation and partial auto correlation plots have been made, and a detailed statistical analysis of results has been conducted.
